Advanced lighting controls – A lighting control system with wired or wireless sensors, or with luminaire integrated lighting controls, that provide occupancy sensor and light level control plus energy metering. [E3T]

Network lighting control system (NLCS) - A lighting control system with multiple components that is connected by a network and offers multiple strategies such as energy reporting and may be integrated with various building systems. [ DLC from NEMA LSD 64-2014] http://www.designlights.org/resources/file/DLC_NLCS_Specification_v1-01

Luminaire level lighting controls (LLLC) – Same as NLCS with required sensors in each luminaire and local processing capabilities. [NEEA]

Luminaire integrated controls – Luminaires with occupancy sensors photosensors, and a controller for each luminaire (integrated or attached). Networking capability and energy/data reporting are optional. [LRC]

Background

8

• Phase 1 Lighting Controls Product Review – Feb. 2015

• Phase 2 Report - Nov. 2015 – 2 brands of LED troffers paired with 3 control systems (2 zone, 1 luminaire-

integrated).

– 1 LED troffer brand with integrated controls.

– All systems were easy to install, but varied in terms of ease of initialization and commissioning.

– Systems did not allow occupants to override light levels without advanced commissioning.

– Manual-on saved energy compared to auto-on.

– Luminaire-integrated controls did not always save more energy than zone controls.

E3T Energy

Efficiency


Phase 3 Purpose

9

• Study 3 commercially-available brands of LED troffers with integrated controls and “plug and play” or “automatic configuration” setup options.

– Ease of installation, commissioning and use using default settings.

– Power demand and light-level monitoring under field conditions.

– Limited to one office space.

E3T Energy

Efficiency


Overall Findings

10

• All 3 lighting systems met or exceeded the target light levels prior to commissioning.

• Once commissioned, measured light levels were similar to the target light levels.

• None of the three systems were easy to commission.

• “Out-of-the-box” (e.g. pre-commissioned) use may not capture potential energy savings.

• Every system had some operational shortcomings with the default settings.

• The systems can potentially meet the desired light levels and save energy if they are properly commissioned.

Lessons Learned

17

Ease of use:

• Two systems were straightforward to install. One system was delivered with incorrect occupancy sensor settings leading to an increased installation time.

• Two of the three systems came with insufficient commissioning documentation leading to an increased commissioning time.

• For one system, pairing the wireless dimming switch was complicated, even with the provided documentation.

Efficiency


Lessons Learned

18

Ease of use:

• False-on events during vacancy periods were seen in all three systems. False-offs also occurred with two of the systems.

• All three systems met or exceeded the target light level before and after commissioning.

• All three systems had some mode of override capability, either with a handheld remote or wireless dimmer. Occupants appreciated override capability, even though they only used it occasionally.

E3T Energy

Efficiency


Lessons Learned

19

Power demand savings:

• Two of the three systems reduced power compared to the baseline. The other system had increased power demand due to false-on events.

• Only one of the systems had the option of a manual-on (vacancy sensor) mode.

• Power factor for all three luminaires was high (> 0.9) even when dimmed. In standby mode, power factor was lower than 0.9.

3 Synthesis & Reporting

• Facilitated De-Brief & Strategy Session

• Final Report

31

Site Visits

There will be two site visits per location:

• The first will last two full days and will happen concurrent with

system installation.

• The second will be sometime after installation – the second

visits will occur at 2, 4 or 8 months into the metering.

Because every site will be unique, we do not expect every site

visit to be the same – we will have a list of research activities /

interviews we hope to accomplish at many sites, but we assume

that not every activity will happen at every site.

Every effort will be made to minimize the impact of conducting

research at sites.

• Wherever possible, research will be scheduled 2 weeks in advance.

General Information

32

Site Visits

Sites That Install LLLC Systems with Energy

Reporting Capabilities

Some sites may choose to install LLLC systems that have energy

reporting capabilities.

The research team recommends adjusting expectations for these

sites in the following way:

• Only meter the portion of the site that is not being captured

through the system’s reporting capabilities

• Integrate the energy reporting of the system with metered

systems when gathering meter data

• Verify accuracy of the system’s energy reporting, and adjust it

mathematically if it is off by more than a certain amount

33

• Observational Activities

• Capture Product Details

• In-Context Interviews

Controls Data and Analysis Project

41

Approach: • Collect and analyze data from verified case studies and manufacturers

• Build database of networked lighting control savings results

• Develop a citable report for energy savings by space type that utilities and other stakeholders can use to:

– establish rebate/incentive levels

– estimate energy savings

– evaluate cost-effectiveness

• Provide reliable, recent data to scale to estimate savings from NLC systems

• Standardized data collection format

• Create a foundation for a growing dataset

Value of Savings Analysis

Before:

• Case studies

• Low confidence

• Low resolution

After:

• Data from many projects

• Standardized data specification format

• High confidence

• High resolution

• Quantify risk and uncertainty

Project Phases

45

Phase II: New Construction (TBD)

• Citable report with data to support DLC members’ incentive calculations for NLCs vs. code in new construction

To bring both Phases I and II to completion and provide benefits to utilities and others,

we need additional funders.
